RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW, Dynamic Range Window

Modem drops connection at least once a day. A tech visited last week and said it's not their fault, the line levels look good. Our connection drops at least once a day while we notice it. Who do I talk to next and how do I remove a charge for a service visit that didn't resolve the problem? After the visit I exchanged the modem for the one the tech recommended and switched to a different router.

Re: RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW, Dynamic Range Wi

The signal stats are o/k. What is the exact make and model number of the cable modem ? Is there a stand-alone router in the mix here ?  If so, for a test, does a computer hardwired directly to the cable modem have the same problem ?

Arris SB8200 with an old ASUS RT-N66R. I bought and then returned both Motorola MB8600 and AUS RT-AX58U.

 

Hard wired devices also drop connection.

What about directly to the MB8600 (no router) as stated ?

Hey, I am going through the same issue but with RCN - with the same modem. Right now to try and fix the issue they are sending a tech out to adjust the power range that my Upload channels are receiving, right now they are too low. 

 

I would live chat with Arris, by the info I gave to them they were able to diagnose it. I don't know if this is a fix yet but I thought I would pass it along.

fwiw, I spoke to an Engineer who said this issue is with the Xfinity side of things and is a bug. It's likely only showing up recently from a firmware update on our modems that's now reporting the error rather than just hiding it. 

 

He seemed to think they would be patching their end of things in the coming months, but for now can be ignored.
